MIDI Gate Length

Reshapes the duration of incoming MIDI notes by controlling when their note-offs occur. Absolute mode enforces a fixed gate length regardless of how long the key is held, giving uniform note durations. Scale mode is causal and extends incoming note-offs proportionally, lengthening notes without ever shortening one that is still being played live. Live parameter changes apply only to new input; already queued note-offs preserve their computed due time.
